LockChime.wav plays on lock, not unlock
Tesla plays your custom LockChime.wav when you lock the car. There is no separate UnlockChime.wav: the factory confirmation tone still handles the unlock event.

How the Tesla unlock chime works
Four things to know before you install, so you get sound on the first try.
How the Tesla unlock chime works
One file, one trigger
The feature is called 'Lock Sound' in Toybox. It fires on the lock event only. If you want something to play when you approach the car, the factory unlock tone is what you hear.
Boombox must be set to USB
Your custom file only plays when Toybox → Boombox → Lock Sound is set to USB. Leaving it on Default plays Tesla's built-in preset instead.
Volume is independent from media
Adjust the lock-chime volume in Toybox using the Boombox slider. It is completely separate from your media volume: set it once and it sticks.
Which Tesla models support a custom lock sound

How to set a custom Tesla lock sound
Step 1
Download LockChime.wav
Pick a sound and download it. Every file arrives named LockChime.wav in 44.1 kHz, 16-bit WAV, the recommended spec for clean playback. The only hard Tesla requirement is a WAV file named LockChime.wav.
Step 2
Copy it into a Boombox folder
On a FAT32 or exFAT USB drive, create a folder named Boombox and place LockChime.wav inside it. Full path: Boombox/LockChime.wav.
Step 3
Plug into a front USB data port
Insert the drive into a front USB data port (the rear ports are power-only). Give the car a few seconds to index the drive.
Step 4
Switch the source to USB
Open Toybox → Boombox → Lock Sound and change from Default to USB. Lock the car to hear it.

Tesla unlock sound: common questions
Is there a separate Tesla unlock sound file?
No. There is no UnlockChime.wav feature in Tesla firmware. The official 2026.8 and 2026.14 release notes do not list separate unlock sounds. Your custom LockChime.wav plays when you lock the car; the factory tone handles unlock.
Does changing the lock sound affect Tesla's horn?
No. The Boombox lock-sound chime is completely separate from the horn. Horn sounds are in a different Boombox menu. Your LockChime.wav only affects the lock chirp.
